I always thought those tiny screws in old lenses were just a pain, but I found out they have a real purpose

I was fixing a 1970s Pentax lens from a flea market find, grumbling about the three tiny screws holding the aperture ring. I figured they were just there to make my life hard. Then I dug into an old repair manual I bought online for five bucks, and it said those screws are actually set to a specific torque to keep the ring's click stops feeling just right. Too tight and the ring feels stiff, too loose and it gets sloppy. I tested it on a junker lens, backing them off a quarter turn each, and sure enough, the clicks went totally soft. It's a small detail, but it shows they really thought about the user feel back then. Has anyone else found a weird little design choice that actually makes sense once you know why it's there?

Honestly, isn't that just overthinking it? I get the whole "they cared about feel" thing, but come on, it's just some screws. If the design was so great, why did they stop doing it? Modern lenses work fine without needing a special manual and a torque wrench. It feels like people just romanticize old stuff and find reasons to call it genius. Maybe it was just the easiest way to assemble it back then, not some deep user experience choice.

Wow, I used to agree with @nancynguyen but this changed my mind.

Hold up, "just some screws" is really missing the point. That old design meant you could fix it yourself with basic tools, not send it back to the factory. NancyNguyen says they stopped so it must be worse, but companies stop doing lots of things that are better for users if it saves them money. They stopped because it's cheaper to glue things shut now, not because it works better. It's the opposite of overthinking, it's simple and repairable by design. That's not romanticizing, it's just good engineering that we lost.
